Although the overall reaction of photosynthesis can be specified with some degree of certainty (CO{sub 2} + H{sub 2}O + light {yields} sugars + possibly other reduced substances), the intermediates through which the carbon passes during the course of this reduction have, until now, been largely a matter of conjecture. The availability of isotopic carbon, that is, a method of labeling the carbon dioxide, provides the possibility of some very direct experiments designed to recognize these intermediates and, perhaps, help to understand the complex sequence and interplay of reactions which must constitute the photochemical process itself. The general design of such experiments is an obvious one, namely the exposure of the green plant to radioactive carbon dioxide and light under a variety of conditions and for continually decreasing lengths of time, followed by the identification of the compounds into which the radioactive carbon is incorporated under each condition and time period. From such data it is clear that in principle, at least, it should be possible to establish the sequence of compounds in time through which the carbon passes on its path from carbon dioxide to the final products. In the course of shortening the photosynthetic times, one times, one …

The processing of eastern oil shale has long been known to require the addition of hydrogen to increase the oil yield. Several researchers, have investigated the use of both high pressure hydrogen and hydrogen donor solvents. Much of the donor solvent work has used pure,compounds such as tetralin and has not addressed the use of-a more realistic solvent such as one derived from the production process itself. The work reported herein is for the research Task 1.2.2, Process Studies, in the Annual Project Plan, October l, 1990--September 30, 1991, of the Cooperative Agreement. In the study, a shale oil-derived, recycle oil was used to mediate the transfer of hydrogen to eastern oil shale. The work was divided into two main parts which correspond to the two main portions of the Hydrogen-Extraction (H-E{trademark}) process: (1) the shale oil extraction which involves the use of a donor solvent to aid in the extraction of the shale oil and (2) the regeneration of the donor solvent to a hydrogen-rich state ready for recycle. The results of the investigation to evaluate shale oil extraction using a shale oil-derived donor solvent suggest that temperature had the, greatest effort on organic conversion. At a temperature of …

It is recognized that the S-50 plant operations are far from standardized and therefore any manual will require continual revision to keep it up to date. Even during the period of writing this first edition, many changes occurred and were incorporated in the manual. Such revisions could delay indefinitely the issuance of the manual and it was felt that in its present form it could be useful in the training of new plant personnel. The specific purpose of the process employed by the Ferclave Corporation in the plant at Oak Ridge, Tennessee, is one of secret information and cannot be released here. It can be stated, however, that the plant operation involves the processing of a chemical substance. This substance is not identified in the plant or in the process but is referred to only as 'material'. Its code designation is C-616. The process in general involves the separation of the raw material into constituents with more desirable properties. It is not necessary to know the name of the material nor the exact nature of the process in order to carry out the operations so this information will not be given in this Manual. The problem involved is to transport …

The following sources of contamination in cooling water of the P-9 plant are considered: (1) Fission recoils, (2) Corrosion of metal, (3) Recoil from aluminum, (4) Induced activity in the water. It is found that for a P-9 plant of 3.5 x 10(4) KW contamination of the river at "X" should not exceed the .1 r criterion unless coating failure occurs. Tables of the amount of coating failure permissible are given as a function of holdup time.

Fermi, Anderson, and Nagle's experimental distribution of Indium resonance neutrons around a point source of fission neutrons in water has been fitted by analytic expressions which are source functions in the two-group, three-group, Fermi and Christy-Wheeler pile theory. The Christy-Wheeler function (exponential followed by a Gaussian) is the best fit; the two-group function (exponential) is slightly better than the Fermi Gaussian.

The O. Hommel Company, of Carnegie, Penna., supplied Mallinckrodt Chemical Works with three types of Mg chips or powder (Type 84, 85B, and 87B) formed by machining Mg ingots. This material was tested and compared with standard New England Lime Mg in a series of reduction runs. A new type of powder (Type 93) developed by the O. Hommel Company during the course of the first experiment was also sert to Mallinckrodt Chemical Works foi preliminary testing. As this was superior to the other tynes tested, a large batch was made up and sent to both Electro Metallurgical Company and Mallinckrodt Chemical Works in order to confirm the preliminary results obtained by Mallinckrodt Chemical Works alone.

Preparation of each source is discussed, and some of their physical properties are given.

A group of radiologists were studied for evidences of radiation damage to the skin of their hands. The technics used were the same as those used for routine hand studies of Argonne National Laboratory personnel and consist of examination of wax impressions of the finger ridges and examination of photographs of the vessels and Papillae in the nail fold. Of the 323 radiologists examined by the first method 48% were found to have ridge abnormalities. The incidence of abnormality increased with years of exposure to radiation up to 100% after 35 years. The irregular use of lead gloves does not give adequate protection against damage of the ridges by radiations. Photographs of the nail fold of 152 radiologists were studied and compared to similar photographs of 101 laboratory workers and of 41 persons over 63 years of age. Some of the abnormalities occurred in all 3 groups. All of the changes which were found among the radiologists were found also in the aged. The incidence of abnormality among the radiologists increased with years of exposure to radiation and exceeded the incidence of abnormality in the aged. No radiologist had normal findings after 30 years of exposure. It is concluded that …

"Equations are presented for obtaining the wall coordinates of two-dimensional supersonic nozzles. The equations are based on the application of the method of characteristics to irrotational flow of perfect gases in channels. Curves and tables are included for obtaining the parameters required by the equations for the wall coordinates. A brief discussion of characteristics as applied to nozzle design is given to assist in understanding and using the nozzle-design method of this report. A sample design is shown" (p. 1).

"Charts are presented for computing thrust, fuel consumption, and other performance values of a turbojet engine for any given set of operating conditions and component efficiencies. The effects of pressure losses in the inlet duct and the combustion chamber, of variation in physical properties of the gas as it passes through the system, of reheating of the gas due to turbine losses, and of change in mass flow by the addition of fuel are included. The principle performance chart shows the effects of primary variables and correction charts provide the effects of secondary variables and of turbine-loss reheat on the performance of the system" (p. 599).

This report contains a review of this work conducted by the Electrodeposition Group for the last six months. Pictures and a discussion of the method used to convert production solutions to postum to hydrofluoride acid solutions of postum are given. Attempts to plate postum in an inert atmosphere by remote control have been made. As yet no successful runs have been completed. Standardization of normal calomel electrodes by comparison to silver-silver chloride electrodes and to hydrogen electrodes is described.

"An investigation was conducted on a turbulent boundary layer near a smooth surface with pressure gradients sufficient to cause flow separation. The Reynolds number was high, but the speeds were entirely within the incompressible flow range. The investigation consisted of measurements of mean flow, three components of turbulence intensity, turbulent shearing stress, and correlations between two fluctuation components at a point and between the same component of different points" (p. 1).
